2개의 simulated된 잠수 실험 즉, 심도 19 ATA와 24 ATA의 고압 Heliox 환경하에서, 4명의 다이 버를 대상으로 하여연 188일간 매일 23:00부터 익일7:00시 사이에 각 다이버에대해서 표준적인 polysomnography를 기록했다. 2개의 잠수조건 하에서 양 실험 모두 해저에서 체재하는 동안 의 밤과 감압하는 동안의 밤 동안에는 총수면시간 (Total Sleep Time)의 단축, 수면효율(Sleep Efficiency)의 감소, 입면잠시(Sleep Latency)의 연장, 중도각성회수 (Number of Awakeningss) 와 감소를 보였지만, 어느쪽도 뚜려한 변화가 있었다라고는 할 수 없었다. 24 ATA 잠수조건에서 의 해저에서 체재하는 동안의 밤과 감압하는 동안의 밤 동안에서는 19 ATA 잠수조건에 비해서 4 단계수면(stage 4 sleep )만 유의한 감소를 보였다. 2개의잠수조건 모두 잠수기간 중에 있어서 는 각성하기 쉬운 상황이었으며, 기본적인 수면패턴에 있어서는 큰 변화는 보이지 않았다.

This paper describes a dwell time calculation algorithm for polishing tool path generation in the small toot polishing process of the axis-symmetrical lens. Generally dwell time control in the polishing machines means that small polishing tool stays for a dwell time at the specific surface position to get the expected polishing depth. Polishing depth distribution on an aspherical lens surface consists of the superposition of the local polishing depth at the each dwell position. Therefore, tool path generation needs each dwell time together with tool positioning data during the polishing tool movements on the aspherical lens surface. The linear algebraic equation of removal depth removal matrix and dwell time is formulated. Parametric effects such as the dwell d interval are simulated to validate the dwell time calculation algorithm.

The aim of this study was to determine the basic perception of Kleingarten house planning of Jeonbuk area. The survey method was used for data collection. The major finding were as follows: 1) Almost all respondents have a very positive attitude the participant of Kleingarten. Many respondents wanted the cheapest price for the Kleingarten rental fee and for the travel time between their home and Kleingarten to be under an hour. 2) Two different size of 45 and 66 $m^2$ were preferable for the house floor plans. The most preferable floor plan type chosen by the respondents was a house design with a terrace and the elderly householders especially preferred a house floor plan with an LDK design. 54.3 per cent respondents liked the log house and 93.3 per cent respondents liked the eco-friendly building materials such as wood, earth (Korean natural earth: whangto), and adobe bricks etc. 3) There were more needs for useful facilities such as a pergola, a grassy lawn, small ponds, a playground for the childrens, patio table settings, etc.
